绑定MapCenter坐标：Center为null

Question

我有Jeff Wilcox静态地图控件：

<jwMaps:StaticMap
            VerticalAlignment="Top"                                   
            Margin="-12,0,-12,0"
            Provider="Bing"                                    
            Foreground="{StaticResource PhoneAccentBrush}"
            Height="200"
            ZoomLevel="1"
            Visibility="Visible"
            MapCenter="{Binding Coordinates}" />

但我有错误System.ArgumentException: Center is null。在这种情况下如何设置默认坐标？坐标有GeoCoordinate类型。

Answer 1

把它放在代码中 将name属性添加到StaticMap示例Name =“staticMap” 然后staticMap.MapCenter =坐标;
